Pay by Steam Skins

Shadowpay offers functionality to refill balance on your website using Steam Skins.

Transaction flow

User clicks the link (button) "Pay By Steam Skin";
Website generates a request to Shadowpay and returns payment link;
Website redirects user to Shadowpay payment link;
User installs the extension or application for automatic, fast, secure trading;
User chooses the skins from his inventory, puts them on sale and waits for buyers. The extension or application sends items to the buyer, the user confirms the trade. For every successfully sold skin your website will receive an IPN with the amount of money for which the item was sold, it's the merchant's responsibility to transfer the amount to the user's account. The amount will also be added to the merchant account on Shadowpay and can be withdrawn.

Getting started

You should generate Public hash and Secret hash on Shadowpay merchant panel.
Set the callback url to where the IPN (Instant Payment Notifications) will be sent.

Create payment link

The above command returns JSON structured as follows:

{
    "token": "a1d579731b5fd7b7cb8f64c641f73111",
    "url": "https:\/\/shadowpay.com\/en\/pay?token=a1d579731b5fd7b7cb8f64c641f73111",
    "status": "success"
}

$params['signature'] = hash('sha256', $params['order_id'] . $params['amount'] . $params['currency'] . SECRET_HASH);

To initiate the payment the client serer should make the following request to get the payment link.

The user then should be redirected to that payment link to complete the payment.

IPN will be sent for each skin the user has sold.

Use this code to validate IPN request.

$string = $_REQUEST['order_id'] . $_REQUEST['amount'] . $_REQUEST['currency'] . $_REQUEST['trade_id'] . SECRET_HASH;
$hash = hash('sha256', $string);

if ($hash !== $_REQUEST['hash']){
    die('wrong params');
}
